The increase in renewable energy sources will require an increase in the operational flexibility of the grid, due to the intermittent nature of these sources. This can be achieved for the gas and the electricity grid, which are integrated by means of power-to-gas and vice versa, by applying gas and other …

BACKGROUND: The predictive validity of the Low Back Pain Perception Scale is determined in two studies in general practice and showed sufficient discriminative ability, although the psychometric properties of the scale have never been established until now. OBJECTIVE: To determine the reliability and …

A new gravitation wave observatory is being built in Japan. This facility is a big Michelson interferometer where the mirrors and sensors will be made cryogenic down to 4 K. The problem is that: the heat cannot be transported out of the mirror by its surroundings because the whole system is in an ultra-high …

A laboratory test setup is built to transfer and actively stabilize an ultrastable signal, obtained from a laser with sub-Hz linewidth, trough a 5 km long fiber link. The fiber noise is measured and compensated via a feedback loop acting on an AOM that can change the frequency (and therefore the phase) …

In The Guardian, Alan Rushbridger compared the future of newspapers to climate change. Five years ago, many climatologists were sceptical whether climate change was a real and serious issue. Today, most scientists agree that global warm ing is a fact of life. In the world of newspapers, at present, almost …

The Food and Agriculture Organisation of the United Nations (FAO) leads international efforts to defeat hunger and malnutrition. On 26 November 1991 the European Union became the 161st Member of FAO, trough Resolution 7/91 which allowed Regional Economic Integration Organisations (REIOs) to accede as …

Mycotoxins are small (MW approximately 700), toxic chemical products formed as secondary metabolites by a few fungal species that readily colonise crops and contaminate them with toxins in the field or after harvest. Ochratoxins and Aflatoxins are mycotoxins of major significance and hence there has …
